Genuinely useful, free marketing courses

A useful roundup titled The 5 Best Free Courses to Make More Money Online on the Jeff Bullas blog highlights a broad range of courses which might be of interest. They cover content writing, computing, email marketing, infographics, PPC advertising, and search engine optimisation. One or two are well known, but a couple were new to me. Many will be useful in your current role, but all will look excellent on a CV and might open new opportunities. And who doesn’t like ‘free’?
